To a-ZZ whom it may concern. i

Be it known that-I; HARRY WV. Emmy,

a citizen'of the United States, andaresident of the city and county of Denver andState of Colorado, have invented certain new and usefullmprovementsin Spark Ari-esters, of which the following is a full clear, and exact description, such as will enable others vskilledlin the art to. which the invention appertains to make and use the same.

-My invention relates to improvements in spark arresters particularly for use on smokestacks. p p I The object of the invention is to provide a spark arrester which may be. used advan tageously .for preventing the sparks from being scattered orblown away from the smokestacks, and at the same timedoes'not interfere with the. draft through the smoke stack; r g,

Inthe drawing forming a part. ofthis specificationy Figure 1' is a vertical sectional view taken on the line 1-1 of Flgure 2;

Figure; 2 is an elevation view partially in section; and Figure 3 is a cross sectional view taken on the line 3-3 of Figure 1.

Corresponding and like parts are referred to in the following description. and indicated in all of the views of the accompanyingdrawings by the same reference characters. The numeral 5 represents the smokestack of a locomotive upon. which the improved spark arrester is adapted to be seated and held in such position that the smoke, as well. 7

as livec'sparks, will be emitted from the Smokestack into the spark arrester. The spark arrester proper; consists in part of a housing 6, preferably constructed of sheet vided with taperingedges 7 and 8, the sheet metal being bent outwardly at right angles to form flanges. A screen 9 is secured to these flanges and occupies a position dlrectly over the top of the smokestack 5. The screen 9 occupies an inclined position whereby the upper portion thereof is in plane parallel with the rear side of the smokestack 5. (See Figure 1.). In other words, the screen 9 completely covers the discharge extremity of the Smokestack, whereby smoke in being emitted from the stack 5 will pass through the screen 9. The sheetmetal housing 6 is hinged to a lower housing 10, as shown by 12; A conical housing 13 is disposed immediately below the houslng 10, and is fastened This sheet metal housing 6 is proto the housing 10 by means of rivets 14:. The conical'shaped housing 13 leads directly into a conduit 15, which may be extended to any suitable location on the locomotive, or into proximity withthe ground, whereby live sparks may be carried through said conduit and collected therein until. such time as they die. The lower end of the conduit 15 .is adapted to be closed by a closure16. which,

is hingedto the conduit as shown by '17. and a fastenlng dev ce 18 is secured to the said closure 16 oppositefthe hinge 17. A housing 19 is fixedly secured to the housing 10. and isadapted to receive the upper extremity of thesmokestack 5. An annular flange2O is secured on the'interior of the housing'19 near the upper extremity of thelatter and projects inwardly at right angles. This flange 20 abutsagainst the upper edge on the smokestack 5 and serves to support the. entire spark arrester on said 'smokestack; The sparkarrester is held in such position means of bolts 21 passed through the housing 19 and'the wall of the smokestack 5. a

The housing 6 is provided with handle member 21*, by meansof which the said housing may be manually tilted to one sideuponthe-hinges 12. In this way, access may be had to the interior of the spark arrester forthe purpose of cleaning or making repairs. A hasp 22 is secured'to thehousing 6 opposite the hinges 12, and by means of which hasp the housing 6 may be locked in position. Guide fingers 23 are'also secured to the sheet metal housing 6 on the'interior of the latter, and are adapted to engage against the housing 10, whereby the hous ng 6 is held firmlv against vibration.

The conduit15 is shown broken out, although it is understood that this conduit may be of any. desired or suitable length so that the discharge extremity thereofmay I v passing through the screen 9 willot course blow the live sparks rearwardly in the housing 6.

While I have described and illustrated herein or specific form or my invention; it

supported by a smoke stack, a secondhousing hingedly connected to the first mentioned housing and having an inclined screen normally extending over the upper end ofthe smoke stack to direct sparks from the smoke'stack to the first mentioned housing, the second mentioned housing with the inclined screen adapted to be swung from its position over the smoke stack .to allow access to the housings.

2. A. spark arrester comprising a housing supported on and surrounding the upper end of a smoke stack, a conduit secured to said housing and offset from the smoke stack, a second housing hingedly connected to the conduit and provided with an inclined screen normally overlying the upper 1. A spark arrester comprising a housing" the smoke stack to allow access to the housings and conduit. i I

3. A spark arrester comprising a housing having an inwardly extending flange adapted to rest upon the upper end of a smoke stack. to support the housing, a conduit sesupported upon and surrounding the upper end of asmoke stack, a conduit secured to said hous ng and offset from the smoke stack, t S6CO DCll1OHS1Hg hingedly connected to the conduit and provided with an inclined screen normally overlying the upper end of the smoke stack to direct sparks therefrom into the conduit, the second men tioned housing having an open top in alignment with the conduit, and a screen secured to said open top, the second mentionedhousmg with its associated screens adapted to be swung from its position over "the smoke stack to allow access to the housings'and conduit.
